Dutch Geofood project to research geothermal heat for lettuce production and fish farming
The Geofood project aims to explore the possibility of using geothermal heat for a system that combines greenhouse horticulture and aquaculture
The Greenhouse Horticulture Business Unit of Wageningen University & Research (WUR) in Netherlands and partners from Iceland, Slovenia and the Netherlands have started collaboration on the Geofood project – a research initiative aimed at investigating whether geothermal heating can be used not just to heat greenhouses, but also to breed fish.
To aid in data collection, an advanced fish farming system was installed at WUR in Bleiswik in 2019. The recirculating aquaculture system (RAS) contains around 10,000 liters of water and thousands of fish.
Data from the system will be monitored, such as water quality, temperature, water consumption, and CO2 generation. The data will be used to validate the energy model developed by WUR for a system that combines geothermal, greenhouse horticulture, and aquaculture.
The application of circular food systems is also being explored for algae production and food processing.
